If I had a pool I would totally try this out. Put a glow stick in a balloon for pool lanterns. Pool party on a Summer night! I think this could work pinned up on the fence of a backyard without a pool, too, so really great idea for any outdoor BBQ/party!
Having burned 5 inches off my hair by using candles in the tub i think this is a fabulous idea! Throw glow sticks in the bathtub and turn off all the lights during bathtime, great idea! Taking a bath by glow-light is soooo de-stressing!
